Structure and working principle of electric wrench impactor
The utility model is characterized in that a chamfer is arranged on the positive switching contact surface of the impact block body and the impact shaft. When the utility model is provided with a chamfering, the contact force is not plane to the plane, and the rotation force of the electric spanner is reduced when the positive gear is rotated, so as to prevent the nut from screwing too tightly and the thread slipping
The utility model discloses an electric wrench impact block structure, including shock and impact block body axis, the impact block body and a rotary connecting sleeve, the impact block body and the connecting shaft through the steel ball impact
The principle is that in the wrench at the same time, similar to the hammer like things on top of frequent percussion, similarity principle and hammer
